Preparation of TiO₂/WO₃ Composite Nanofibers by Electrospinning

Abstract:

Preparation of cellulose acetate (CA)/TiO₂/WO₃ composite nanofibers via sol-gel with electrospinning process for improving the photocatalytic efficiency was conducted. CA was removed from fibers by a heat treatment. Microstructure and elemental composition of TiO₂/WO₃ nanofibers were evaluated by scanning electron microscope (SEM) and energy dispersive microscopy (EDX), respectively. The results showed that the nanofibers of TiO₂ and WO₃ were achieved with the average diameter range of ca. 310-701 nm and both TiO₂ and WO₃ are well dispersed along fiber length, confirmed by an EDX analysis. The results also showed that the smoothness of fiber surface decreased with decreasing WO₃contents. The photocatalytic activity of the materials were also tested for methylene blue degradation. TiO₂/WO₃ exhibited the highest activity comparing to pure TiO₂ and WO₃. Moreover, it was found that a TiO₂/WO₃ specimen possessed the energy storage ability as a result, it showed the photocatalytic activity in the absence of light.
